## Why Battery rated in Ah (Ampere hour) and not in VA.

Why Battery rating in Ah (Ampere hour) and not in VA. Battery stores charge in the form of chemical energy and then converts it into electrical energy to utilize for a specific time. The amount of available charge is the capacity of a cell or battery which may be expressed in Ah (Ampere-hour). Moreover, in a charged battery, the numbers …

## Why we can’t store AC in Batteries instead of DC?

Why we can’t store AC in Batteries instead of DC.or Can we store AC in batteries instead of DC? We cannot store AC in batteries because AC changes their polarity up to 50 (When frequency = 50 Hz) or 60 (When frequency = 60 Hz) times in a second. Therefore the battery terminals keep changing Positive (+ve) becomes Negative (-Ve) …

## A Voltmeter, an ammeter (Ampere meter) and a battery cell are connected in series. It is observed that ammeter practically shows No Deflection. Why?

A Voltmeter, an ammeter (Ampere meter) and  a battery cell are connected in series. It is observed that ammeter practically shows No Deflection. Why? Due to the large resistance of the voltmeter, the circuit resistance becomes very high. As a result, very small current will flow in the circuit. this small current f on passing through the coil of voltmeter …
